GeoPark Ltd., a leading independent Latin American oil and gas explorer, operator and consolidator, said Feb. 4 it has made a discovery in the new Jauke Oeste gas field in the Fell block (GeoPark operated, 100% WI) in Chile.
GeoPark drilled and completed the Jauke Oeste 1 exploration well to a total depth of 9,596 ft (2,924 m). A production test, through different choke sizes, in the Tobifera formation resulted in an average production rate of 4.4 million standard cubic feet per day of gas (MMcf/d)—or 729 barrels of oil equivalent per day (boe/d)—and 52 bbl/d of condensate with a wellhead pressure of 3,141 pounds per square inch. Additional production history is required to determine stabilized flow rates of the well and the extent of the reservoir. Surface facilities are in place, the well is in production, and the gas and condensate are already being sold to offtakers.
The Jauke Oeste gas field is located approximately 1 km north of the Jauke gas field, which is currently producing approximately 8.4 MMcf/d from two wells (or 1,400 boe/d). Jauke and Jauke Oeste gas fields are part of the large Dicky geological structure in the Fell block—opening the potential for multiple development drilling opportunities.
Additional exploration activities will be carried out in Chile during first-quarter 2020 with a focus on oil prospects. GeoPark will be spudding the Leun 1 exploration well in the Flamenco block (GeoPark operated, 100% WI) in February 2020, to be followed by the Huillin 1 exploration well in the Isla Norte block (GeoPark operated, 60% WI) and the Koo 1 exploration well in the Campanario block (GeoPark operated, 50% WI).
Operators overlooking the potential in mature fields could be missing out on increased returns and productivity, according to Brazil’s top operators.
This latest awars covers the SURF scope for Field 6, but the SURF work for Fields 7-9 still remains on the company’s subsea opportunity list, Tudor, Pickering, Holt analysts said.
Operators are putting a stronger emphasis on diagnostics of their hydraulic fracturing operations to make improvements and stay competitive.
